    • Combined effects of crude oil exposure and warming on eggs and larvae of an arctic forage fish 

      Giebichenstein, Julia; Teisrud, Ragnar; Laurent, Jennifer Malica; Frantzen, Marianne; Meador, James P.; Sørensen, Lisbet; Hansen, Bjørn Henrik; Reinardy, Helena C.; Laurel, Benjamin J.; Nahrgang, Jasmine (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-16)
      Climate change, along with environmental pollution, can act synergistically on an organism to amplify adverse effects of exposure. The Arctic is undergoing profound climatic change and an increase in human activity, resulting in a heightened risk of accidental oil spills. Embryos and larvae of polar cod (Boreogadus saida), a key Arctic forage fish species, were exposed to low levels of crude oil ...

    • Effects of mine tailing exposure on early life stages of cod (Gadus morhua) and haddock (Melanogrammus aeglefinus) 

      Farkas, Julia; Nordtug, Trond; Svendheim, Linn Hjelmeland; D Amico, Elettra; Davies, Emlyn John; Ciesielski, Tomasz Maciej; Jensen, Bjørn Munro; Kristensen, Torstein; Olsvik, Pål Asgeir; Hansen, Bjørn Henrik (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-06-05)
      Mining and processing of minerals produce large quantities of tailings as waste. Some countries, including Norway, allow disposal of mine tailings in the sea. In this study we investigated the impacts of tailings from a calcium carbonate (CaCO3) processing plant on early live stages of haddock (<i>Melanogrammus aeglefinus</i>) and Atlantic cod (<i>Gadus morhua</i>). Fish eggs (3 days post fertilisation; ...

    • Spawning time in adult polar cod (Boreogadus saida) altered by crude oil exposure, independent of food availability 

      Strople, Leah Catherine; Vieweg, Ireen; Yadetie, Fekadu; Odei, Derrick Kwame; Thorsen, Anders; Karlsen, Odd André; Goksøyr, Anders; Sørensen, Lisbet; Sarno, Antonio; Hansen, Bjørn Henrik; Frantzen, marianne; Hansen, Øyvind J; Puvanendran, Velmurugu; Nahrgang, Jasmine (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-03)
      Fish early life stages are well known for their sensitivity to crude oil exposure. However, the effect of crude oil exposure on adults and their gametes during their spawning period is not well studied. Polar cod, a key arctic fish, may be at risk for crude oil exposure during this potentially sensitive life stage. Additionally, this species experiences lower food availability during their spawning ...
